For combining 3d printing directly on CNC I would not suggest it, CNC milling is dirty, you would need to clean the part, possibly heat it up... and I do not believe that would stick well... printing and milling separately would yield better result.

I setup my 3D printer with a single Ballscrew for the Z axis.
A while back, I read about a polymer system similar to a ball screw (without the ball bearing) and I am considering if I should make the upgrade. Sadly I can't seem to find the info.
If anyone knows what I am talking about I would appreciate some pros, cons and the name of that system.
Thanks

The path are exactly the same except that you do a single twist at the front (on both side of the belt to avoid contact where the 2 belt crosses).
You still need some height difference but only a few mm...
I am not at home ATM, here is an old image and videothat I got from when I started... I will upload some more later.

I had to rebuilt my CoreXY recently (had a misalignment on the z-axis).
Since then I had some layer shifting and I was hoping to get some info on some test that could indicate if the belt is too tight or too loose.
I am using the single belt setup.
Thanks

I am going to update my Z-axis.
Currently I am using 2x MGN12 rails with one SFU1204 Ballscrew.
I had to print the bracket to mount everything together and my bed on occasion still staggers (I assume that I am not 100% aligned...).
I decided to change my MGN12 rails and blocks for SBR12 with SBR12UU blocks, apparently my ballscrew housing would match the height of the SBR12UU blocks.
My questio

My 3D printer is pretty solid...
I went overboard with the 90 degrees bracket, using an aluminum top plate for the X & Y movement, multiple cross support...
The structure itself is made of 2020 aluminum.
Why are you saying that I would messup my printer?

I built a CoreXY 3D printer.
Print really good, added a small motor for PCB milling, works pretty good for PCB and soft wood.
I want to upgrade for harder wood, aluminum and possibly steel...
I am looking on Aliexpress and I see a wide range of specs and was hoping to find the required wisdom for me to choose the appropriate setup.
ATM, the one that I am considering the most CNC Spindle

I am building a CoreXY.
I am mostly done and my SSR got lost in transit. While I was waiting for my part I saw Tom video on the subject. Now that I have to reorder, I am considering using Mosfet instead of SSR.
I have some question on the subject. I am planning to use it with a 24V 350W power supply and a 350W heated bed.
Some people use Mosfet board and other Mosfet transistor. Tom (see link

I'm glad you got it working. DuwtWebControl 1.14a is the correct version to work with RRF 1.17e. M997 S1 and M997 S1 are for the Duet WiFi only.
For the Duet 0.8.5 do I require to do something to install the web control or do I just need to setup the network specs?

I was finally able to run the stepper motors, my 0.8.5 isn't blown...
Also I would require some help on how to install the Web Controler.
I copied the DuetWebControl-1.14a to the /www
I copied the files DuetWebControl-Master to the /sys
When I am trying to run M997 S2 to install it doesn't install

ok Thanks for the comments...
Here is what I have done and the result.
I upgraded (bossac) to the 1.17e.bin. the web service that I found was 1.14a.bin unsure if it's the right version...
Since I am learning I copied the 1.14a to the /sys folder and tried the M997 S2 to install the web service and I got QuoteInvalid module number '2'.
Have I done anything wrong? should I downgrade to 1.14a for

Hi, I would like some assistance.
I am currently building a CoreXY 3D printer.
The board that I am using is the Duet 0.8.5.
I am going to run with 2x power supply 24V but, while I am learning, I am using an old ATX 12V power supply. At the moment, I can't seem to run my stepper motors or fan with Ponterface. I am afraid that my 0.8.5 might be damaged is there a way to run a diagnostic on the

I am currently building a CoreXY with duet 0.8.5.
The heatbed that I got is a 24V 350W 350 x 350mm. I currently have 2 power supply:
24V 150W power supply (3D printer) 24V 350W power supply (heatbed)
I was hoping to use the 350W for the bed and the 150W everything else.
From what I found, it is possible if I use a SSR (Solid State Relay). from my understanding I would require 1 for the 350W of

I am using a 24V 350W power supply. The size of the silicone heating bed is currently of 350mm x 350mm, what amount of Watts would you suggest?
Also, I have read on the Duet RepRap page: "Processor voltage is 3.3V and inputs are not protected, so using sensor with higher voltage need reliable protection. Optocoupler or diode protection may be more reliable than voltage dividers." any one would h

Thank you for the intel.
I have been looking and I recently learned (CoreXY project) that I require all the info prior to starting.
Do you guys know a good website with sufficient information on CO2 laser for the mounting, security, consumables,...
Also if you know a good and reliable online store would be appreciated.
Thank you

Has the title says, I am currently building a CoreXY and I would like to add a laser cutter/engraver. I would require information and suggestions on the laser to go with...
What I want is engraving /cutting 2-3mm plywood and transparent acrylic. I will be using a Duet WIFI.
Only one thing, I do not want a CO2 laser, I have considered it and would prefer getting experience prior to start using t

Hi I am new here and I have a 3d printer project...
I am curious on if anyone knows how to fit a hotwire cutter (for acrylic) on a CoreXY without adding a second XY axis under the bed (which would now require to be removable).
My idea is to have the frame of the bed with 90 degrees angle to hold the hotbed or the acrylic sheet. the hot wire would be controlled by 2 identical XY axis (and wish f
